Answer:
False
Explanation:
The sequence of amino acids in a protein is determined by the DNA and the structure of protein thus formed is a linear sequence. These linear structures undergo structural changes due to the formation of bonds between the constituent molecules.
When bonds are formed by the interactions between the CO group of one chain and the -H group which forms the backbone is known as the secondary structures. Two types of arrangements arise of this that is the helical and pleated sheet.
When the bonds are formed between the side groups or the R group of the amino acid therefore the amino acid structure formed is known as the tertiary structure.
Thus, false is the correct answer.
Answer:
The foaming in the elephant toothpaste demonstration means that a gas is produced. Production of a gas is a clue that a chemical reaction has occurred. The water vapor in the genie-in-a-bottle demonstration also shows the production of a gas.
Answer: In biology, a gene is a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. Genes and DNA are different..... DNA is the molecule that is the hereditary material in all living cells. Genes are made of DNA, and so is the genome itself. A gene consists of enough DNA to code for one protein, and a genome is simply the sum total of an organism's DNA.
Hope this helps..... Stay safe and have a great day/night!!! :D
Answer:
A nutrient is a chemical substance that organisms require to live.
Answer: To allow efficient distribution of materials within the body
Explanation:
Circulatory system in mammals especially human provides an efficient way of distribution of materials within the body.
This is made possible by blood and lymph which represent the media for circulation in humans
